CVE-2025-10909 is a cross-site scripting vulnerability identified in the Mangati NovoSGA software, specifically affecting versions 2.2.0 through 2.2.9. The vulnerability resides in an unspecified function within the /admin directory of the SVG File Handler component. Attackers can exploit this flaw by manipulating the 'logoNavbar' or 'logoLogin' parameters, which are likely used to customize or display logos in the administrative interface. This manipulation allows injection of malicious scripts that execute in the context of the victim's browser, leading to potential session hijacking, credential theft, or unauthorized actions performed with the victim's privileges. The vulnerability is remotely exploitable without requiring authentication, but it does require user interaction, such as an administrator visiting a crafted URL or page. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:H indicates high privileges required, but the description states no authentication needed, so this may be a discrepancy), user interaction required (UI:P), and limited impact on confidentiality and availability but some impact on integrity. Although no active exploitation has been observed in the wild, the availability of a public exploit increases the risk of targeted attacks. The lack of an official patch at the time of publication necessitates immediate mitigation efforts by affected organizations.

For European organizations, this vulnerability poses a risk primarily to the integrity of administrative sessions and the trustworthiness of the NovoSGA administrative interface. Successful exploitation could allow attackers to execute arbitrary scripts in the context of administrators, potentially leading to credential theft, session hijacking, or unauthorized administrative actions. This could disrupt administrative operations or lead to further compromise of internal systems. Given that NovoSGA is an administrative management system, exploitation could affect data integrity and operational continuity. The impact on confidentiality and availability is limited but not negligible, especially if attackers leverage the XSS to conduct phishing or social engineering attacks against administrators. Organizations in sectors with high reliance on NovoSGA for administrative tasks, such as public administration, education, or medium-sized enterprises, may face increased risk. The presence of a public exploit elevates the urgency for mitigation to prevent opportunistic attacks.

1. Immediately restrict access to the /admin interface of NovoSGA to trusted IP addresses or VPN users to reduce exposure. 2. Implement web application firewall (WAF) rules to detect and block malicious payloads targeting the logoNavbar and logoLogin parameters. 3. Apply strict input validation and output encoding on all user-controllable parameters, especially those related to logo customization in the SVG File Handler component. 4. Monitor administrative access logs for suspicious activity or unusual parameter values indicative of exploitation attempts. 5. Educate administrators about the risk of clicking on untrusted links or opening suspicious URLs related to the NovoSGA admin interface. 6. Coordinate with Mangati for timely release and deployment of official patches or updates addressing this vulnerability. 7. Consider deploying Content Security Policy (CSP) headers to limit the impact of potential XSS attacks by restricting script sources. 8. Conduct regular security assessments and penetration tests focusing on web interface vulnerabilities to identify similar issues proactively.
